Proof of the Uniqueness of Bicone and Tri-Bicone Nested Cosmological Topology Based on Six-Line Hexagram Projection and the PFUSRC Axiom System

This paper strictly adheres to the axiomatic system of the PFUSRC Ultimate Unified Theory and follows the core mapping axiom: the Bagua and Sixty-Four Hexagrams are not abstract symbols, but a 2D projection model of the cosmic closed bicone high-dimensional topology. Based on six-line hexagram mathematics, prime rivet topological anchoring, ion spin hierarchy, and constraints of a closed rotating universe, this paper systematically proves that under the cosmic axioms of no first cause and four-dimensional Weizhao initiation, the coaxial nested tri-bicone is the unique steady-state topology of the universe. All non-cone geometries are invalidated. Dimensions can only grow by seam nesting rather than external superposition. The closed bicone ensures yin-yang symmetric self-stabilization, and the tri-bicone realizes high-dimensional stratification and observation bias compensation. Prime rivets form the rigid topological skeleton. This work is fully isomorphic and self-consistent with the PFUSRC framework, completing the unified closed loop of cosmic structural ontology.
